IMPROVEMENT vIN RAILWAY-RAIL CHAIRS.

Specification forming part of Letters Patent No. 217,718, dated July 22,1879; .application liled May 2S, 1879.

To all whom fit may concern:

Be it known that I, JULIUs WoD1sKA,of New York, in the county and Stateof New York, have invented a new and Improved Chair for Railroad-Rails,of which the following is a specification.

In the accompanying drawings, Figure l is a top view of my improvedchair i'or rails, showing the same attached to the sleeper of arailroad-track. Fig. 2 is a vertical central section of the same on theline c c, Fig. 1; Fig. 3, a vertical central section of the same on theline k k, Fig. l; and Fig. 4, a vertical transverse section on the linec lc, Fig. 1.

Similar letters of reference indicate correspending parts in all thefigures.

This invention relates to an improved cushioned support or chair, to beinterposed between the sleepers and the rails of an elevated or otherrailroad, to prevent the transmission of vibration from the rails to thesupporting-frame of the track, and the consequent noise; also, tocounteract as much as possible the vibration of the rails.

The invention consists in the combination of -a box-shaped chair,adapted to be fastened upon the sleeper, and having two notched sides,of which one side is removable, and an open top with an interior cushionand a metallic top plate, to which the rail may be fastened.

The invention also consists in the details of improvement hereinaftermore fully pointed out.

In the drawings, the letterA represents my improved chair or supportforrails. This chair is made box-shaped, of metal or other strongmaterial, and adapted to be placed upon or sunk into a recess in theface of the sleeperB.

rlhe box-shaped chair A, which is preferably of rectangular form, isopen 011 top, and has one of its sides, a, made removable.

Theremovable side amay be secured in place by four (more or less) bolts,b b, that project from the side of the box A and pass through holes inthe plate a, and by nuts d, which are screwed upon the ends of the boltsb against the face of the plate a.

I prefer to extend the plate a and the opposite plate, e, of the box Adownward below the bottom of the box, so that said plates bear againstthe sides of the sleeper B, as shown in Figs. 3 and 4, and prevent thechair from bein g loosened by the vibration caused by the trains.

The removable plate o is made L-shaped, being made in one piece, withtwo wings or end plates, ff, which extend across the top of the box A,as shown in Fig. l. The free ends ofthe wings f f extend beneath, andare secured in place by hook-shaped projections g, formed on the upperedge of the plate e. Between the wings ff the top of the box A is opento allow for the admission of the rail h., and the side plates, et andc, are recessed at their upper edges in line with said top opening, toallow Jfor slight up-and-down play of said rail.

It will be seen that by removing the nuts d and the plate a, with itswings ff, one side and the top of the box A are entirely exposed,

and free access to said box obtained.

Within the box A is placed (the side a being previously removed) acushion, t', of rubber or other elastic material. Upon this cushionrests a metallic plate, j, which is made of the same width as theinterior oi' the box A, so that said plate j is capable of up-and-downbut not of lateral play.l The upper face of the plate j is provided witha groove, or is otherwise adapted for the reception of the rail h, whichis rigidly attached to said plate by bolts l and clamps m, or in anyother manner. After the cushion i and top plate, j, have been placedwithin the box A, the side plate, a, is fastened to the box in propermanner, and confines said cushion and top plate within the box.

It will be seen that the above-described railway-chair allows slightup-and-down play of the rail h on its cushioned support. It effectivelyprevents the transmission of vibration from the rails to the sleepers B,and the consequent noise. At the same time any one chair on the trackmay be opened for the removal and replacement of the cushion, or forother repairs, or any one entire chair may be re moved withoutdisturbing the remaining chairs or the track, or even the rail. Thechair is, moreover, compact and of simple construction.

I claim* 1. The combination of the box-shaped raila way-chair A, havingan open top, and the recessed side plates, u and e, of Which the sideplate, a, is removable, With the cushion i and bearing-plate j,substantially as herein shown and described.

2. A railroad-chair, A, having the removable side co, which carries thetop Wings, f f, in combination with the side e, having hooks g, and withthe cushion i and top plate, j, substantially as specified.

3. The box-shaped railway-chair provided with downwardly-projectingplates a and e, which straddle Jche sleeper, and of which lhe plate a isremovable, substantially as herein shown and described.

JULIUS WODISKA.
